We held three special previews for the Age of the Dinosaur exhibition on Wednesday, 20 April. As you can imagine, it was a pretty frantic day for all involved. There was a fab response and lots of photos too.

Cheeky Ben Brockman (actor Daniel Roche) star of the Outnumbered TV comedy series, finds his rightful place in front of the exhibition's roaring animatronic Tarbosaurus at the special preview on Wednesday night.

Press and media came first thing in the morning armed with film crews and cameras. Some of you may have caught some of the great coverage in the press and on TV yesterday.

Mid-morning, for the first time we invited some of our Twitter followers along with their families to share their thoughts on the exhibition.There was some enthusiastic feedback. Here are some of their comments:

Our thanks to all our Twitter guests who attended the #nhmdino event for their enormous enthusiasm and support. You can read more of what they had to say here on Twitter.

Then came the special evening preview where celebrities and children leapt at the chance to appear in a roaring session in front of our biggest and most ferocious animatronic in the exhibtion, Tarbosaurus.

Emily Smith, our Head of Communications, says: 'It was a fabulous evening with plenty of fun from dino snacks, a swamp lucky dip to piñata bashing. I was quite scared at first but my mind was put to rest when I realised there were responsible palaeontologists in charge of the dinosaurs.'
